Pendahuluan
Web security reconnaissance adalah fase paling krusial dalam bug hunting dan penetration testing. Di tahun 2026, tools dan teknik terus berevolusi seiring kompleksitas aplikasi web modern.
Passive Reconnaissance
Certificate Transparency Logs
curl -s "https://crt.sh/?q=%25.target.com&output=json" | jq '.[].name_value' | sort -u
DNS Enumeration
subfinder -d target.com -all -silent
amass enum -passive -d target.com
Technology Fingerprinting
wappalyzer https://target.com
whatweb https://target.com
Active Reconnaissance
Directory Bruteforce
ffuf -u https://target.com/FUZZ \
-w directory-list-2.3-medium.txt \
-fc 404,403 -t 100
Parameter Fuzzing
ffuf -u 'https://target.com/api/v1/users?FUZZ=test' \
-w params.txt -fc 400
CORS Testing
curl -sI "https://api.target.com/" \
-H "Origin: https://evil.com" | grep -i "access-control"
Tools Wajib 2026
| Tool | Fungsi |
|---|---|
| Subfinder | Passive subdomain enum |
| ffuf | Fast web fuzzer |
| nuclei | Vulnerability scanner |
| httpx | HTTP probe + technology detect |
| katana | Web crawler |
| gau/waybackurl | Archive URL gathering |
Pipeline Automation
subfinder -d target.com | httpx | nuclei -t cves/ -o vulns.txt
Kesimpulan
Recon adalah kunci sukses bug hunting. Kombinasi passive + active reconnaissance dengan pipeline automation akan mengungkap permukaan serangan yang lebih luas.
